 Palpi fringed, very long, nearly vertical, rising very high above the 

 head ; second joint very slightly curved ; third full half the length 

 of the second, with which it forms a slight angle, apparently some- 

 what securiform, the third joint being bare at the tip and very acute.

 hind wings. Wings rather long. Fore wings subfalcate; the four 

 lines very incomplete, indicated by some black points ; interior and 

 exterior lines forming two black triangular spots on the costa, and 

 having a black costal spot between them; a black apical spot; mar- 

 ginal lunules black; reniform mark reddish ferruginous, with 

 a smaller black spot adjoining its outer side. Hind wings beneath

This species differs much from all the others in structure, 

 and will form a peculiar group in the genus.
